Mphamvu yamagetsi ndi mphamvu yosunga malamulo

Kupatula mphamvu yokoka ndi mphamvu ya masika, chitsanzo china cha mphamvu yosunga zinthu mwadongosolo ndi mphamvu yamagetsi. Kuti mumvetse bwino chifukwa chake mphamvu yamagetsi imatchedwa mphamvu yosunga zinthu mwadongosolo, werengani kufotokozera uku.

Tiyerekeze kuti pali ma plate awiri odzaza ndi magetsi monga momwe zasonyezedwera pachithunzichi, plate yakumanzere ili ndi positive charge ndipo plate yakumanja ili ndi negative charge.n zoipa. Muvi pakati pa mbale zonse ziwiri ndi mizere yamagetsi yang kuchokera ku chaji yabwino kupita ku chaji yoyipa. Chaji yabwino ili pafupi ndi mbale yoyipa.

Malo amagetsi chifukwa cha chaji imodzi

Kuwerengera munda wamagetsi Chopangidwa ndi mphamvu imodzi yokha, gawo loyamba ndikusankha pamwamba pa Gaussian wa radius r pomwe pakati pa mphamvuyo pali mphamvu imodzi yokha. Malo a pamwamba pa mphamvuyo ndi 4.r².

Mphamvu yamagetsi yochokera pakati pa mpira imalowa molunjika pamwamba pa mpira kotero kuti njira yamagetsi yosinthira magetsi ndi Φ = E A. Njira ya lamulo la Gauss ndi Φ = Q / ε _o

Mphamvu yamagetsi yomwe ili patali ndi r kuchokera pa chaji imodzi ndi iyi:

Mu nkhani ya lamulo la Coulomb, mphamvu pakati pa magetsi inaphunziridwa. Powunikiranso minda yamagetsi, mtundu wina wa lamulo la Coulomb unakambidwa, womwe unafotokozedwa kudzera mu equation F = q E, pomwe F ndi mphamvu yamagetsi, q ndi mphamvu yamagetsi, ndipo E ndi mphamvu yamagetsi. Tinganene kuti lamulo la Coulomb ndi lamulo la fizikiki lomwe limafotokoza ubale pakati pa mphamvu yamagetsi (q) ndi mphamvu yamagetsi (E).

Zitsanzo za mafunso ndi njira za lamulo losunga mphamvu zamakanika, mphamvu zomwe zingatheke za kasupe, makina osavuta

Lamulo losunga mphamvu zamakanika

1. Chinthu chimakhala ndi mphamvu yosalekeza ya makina, kuwonjezera mphamvu ya kayendedwe ka zinthu, komanso kuchepetsa mphamvu yokoka. Chinthucho chili mu mkhalidwe wa….

1. diam
2. pita mmwamba
3. pita pansi
4. kukwera mmwamba mwachangu

Zokambirana
Mphamvu ya kinetic ikakula, liwiro la chinthucho limakula, ndipo mphamvu yokoka ikachepa, kutalika kwa chinthucho kumachepa pamwamba pa nthaka. Izi zimachitika pamene chinthucho chikuyenda kuchokera kutalika kwina kupita pansi.

Mphamvu yamagetsi ndi chinthu chomwe chimapangidwa ndi mphamvu yamagetsi ndipo chimakhudza malo ozungulira mphamvu yamagetsi, komwe mphamvu ya mphamvu yamagetsi imamveka ndi mphamvu zina zamagetsi. Mphamvu ina yamagetsi ikapezeka mu mphamvu yamagetsi, mphamvu ina yamagetsi imamva mphamvu yamagetsi.

Tanthauzo la munda wamagetsi, monga momwe tafotokozera m'nkhani yokhudza minda yamagetsi, lingamveke bwino m'maganizo, komanso lingaganizidwe m'maganizo. Kuti muone ngati munda wamagetsi uli ndi minda yamagetsi, mizere yamagetsi imaperekedwa. Mizere yamagetsi ndi mizere yozungulira mphamvu yamagetsi kuti iwonetse kupezeka kwake. Chifukwa cholinga chake ndi kuwonetsa kupezeka kwa munda wamagetsi, pali ubale pakati pa mizere iyi ndi munda wamagetsi. Mwanjira ina, kukula ndi komwe munda wamagetsi uli kungathe kufotokozedwa kudzera mu chithunzi cha mizere yamagetsi.

Mu nkhani ya Electric Field , takambirana tanthauzo ndi njira ya magetsi yomwe ingagwiritsidwe ntchito kuwerengera mphamvu ya magetsi yomwe imapangidwa ndi chaji imodzi yamagetsi, ma chaji angapo amagetsi kapena kugawa kwa ma chaji amagetsi. Kuwerengera mphamvu ya magetsi yomwe imapangidwa ndi chaji imodzi yamagetsi kapena ma chaji awiri amagetsi kumathetsedwa mosavuta pogwiritsa ntchito njira yamagetsi yamagetsi. Ngati chomwe chimawerengedwa ndi mphamvu yamagetsi yomwe imapangidwa ndi kugawa kwa chaji yamagetsi, kuwerengera kumakhala kovuta kwambiri ngati mukugwiritsa ntchito njira yamagetsi yamagetsi koma ndikosavuta ngati mukugwiritsa ntchito lamulo la Gauss .

Zokambirana
Kusamutsa kutentha kudzera mu conduction ndi kusamutsa kutentha komwe kumachitika kudzera mu kugundana pakati pa maatomu/mamolekyulu omwe amapanga chinthu. Mwachitsanzo, taganizirani za chitsulo chotenthedwa. Mbali imodzi ya chitsulo imakhudzidwa ndi lawi ndipo mbali inayo imagwiridwa. Ngakhale kuti mbali inayo ya chitsulo chomwe chikugwiridwa sichikugwirizana ndi lawi, chifukwa kutentha kumadutsa kudzera mu chitsulo, mbali inayo ya chitsulo chomwe chikugwiridwa chimamva kutentha. Kodi kutentha kumasuntha bwanji kuchokera mbali imodzi ya chitsulo kupita ku inayo?
Nsonga yachitsulo yotentha imalandira kutentha kowonjezera. Kalori ndi mphamvu yomwe imayenda mwachibadwa kuchokera ku zinthu zomwe zili ndi kutentha kwakukulu kupita ku zinthu zomwe zili ndi kutentha kochepa. Mphamvu yowonjezerayo imapangitsa maatomu/mamolekyulu omwe amapanga chitsulo kugwedezeka kwambiri kuchokera pamalo awo ofanana. Pamene akugwedezeka kwambiri, maatomu/mamolekyulu amagundana ndi maatomu/mamolekyulu oyandikana nawo, zomwe zimapangitsa maatomu/mamolekyulu kugwedezeka kwambiri ndikupeza mphamvu zambiri. Njirayi imapitirira mpaka kutentha kufika pa nsonga ya chitsulo chomwe chikugwiridwa.
